The Central Processing Unit (CPU) is the primary circuitry responsible for processing instructions and performing calculations in a computer. It acts as the brain of the system, executing program instructions and managing data processing tasks.
Random Access Memory (RAM) is the temporary storage used by a computer to store data actively being used and processed. It allows for quick access to information, enhancing the system's performance during active tasks.
Hardware refers to the physical components of a computer, including the motherboard, CPU, memory, and other tangible parts. It is the opposite of software, which represents the programs and applications running on the system.
A program is a set of instructions that a computer can execute to perform a specific task or operation. It represents the sequence of steps that the computer follows to carry out a desired function.
Compilation is the process of converting human-readable instructions, written in a high-level programming language, into a format that a computer can execute. This process involves creating an executable file from the source code.
Cache is a small, fast storage area within the CPU that stores frequently accessed data for quick retrieval. It helps improve the overall speed and efficiency of the computer's data access.
A username is a unique string of characters used to identify a user on a computer system. It is often paired with a password to secure access to personal accounts.
A Local Area Network (LAN) is a computer network that covers a small geographic area, such as a single building or campus. It allows connected devices to share resources and communicate efficiently.
Antivirus software is designed to detect, prevent, and remove malicious software (viruses, malware) from a computer system. It helps maintain the security and integrity of the system.
Debugging is the process of systematically finding and fixing errors in computer programs. It involves identifying and correcting issues in the code to ensure the program functions as intended.
